Experience the power of gravity with Gravitrax, the interactive track system! With the GraviTrax toys, you will encounter a new interactive track system that will allow you to design and build your own race tracks and experiment with gravity, magnetism, and kinetics to propel your gravity sphere to the finish. Gravitrax has a variety of tiles, levels, and tracks with features you can control using the speed of each gravity sphere. It’s the new line of STEM (science, technology, engineering, and maths) toys from Ravensburger! The open-ended building concept offers endless possibilities to design a different track every time you play. Shop for Gravitrax toys here at Mr Toys and enjoy playing with gravity in a whole new way!
